Guide to Quantitative Research Critique

Guide to Quantitative Research Critique

There are lots of research out there. Some of the research is good and some not so good. The areas below should be a guide for you as you are evaluating quantitative research to help you determine if the research was done in a valid, non-partisan way which adds to the body of nursing practice or knowledge. Each of the following sections should have a brief discussion and examples from the research article as appropriate to support your evaluation of that section. Each section does not have to be addressed in the research article to make it good research but the preponderance of the evidence from the article, based on the following analysis, should be evident in the article. Generally a research critique is about 2-3 pages with each section of the analysis clearly identified ( by headings) and discussion.

Topic/ Heading Discussion to include in your analysis of the article
Introduction Here state in 200 words or less the name and author (s) of the article, what the

purpose of the study, and what your paper will discuss

Article Title Does the title clearly tell you what the research is about
Authors Credentials What are the credentials of the authors: What does it tell you about their research experience? Does the authors have a background in the subject area?
In your own words state the purpose of the study Is the purpose clear? Relevant to your practice? Was there a need for the study? Will the study improve nursing practice and / or add to the body of nursing knowledge?
Literature Review Does the literature review appear comprehensive in nature? Is the literature review current ( consider the date the article was published- as a general rule literature should be no more than 5-7years old from the time the article was written. Are there benchmark articles ? Are the majority of the articles primary or secondary sources? Is the literature review logical in organization, is there an introduction and summary?
Theory, framework concepts and the relationship to nursing Is there an identified theoretical basis or concepts/ model used to help develop the research? If so it clearly stated? If there is no stated theory or framework, can you identify how the data will be collected, what the population is, and the plan for conducting the study? Is there a clear link between the research question/ purpose and the theoretical / conceptual framework?
Research question or hypothesis Is the research question clearly stated and appropriate? Does the question align with the purpose of the study? If there is a hypothesis, is the hypothesis clearly stated and reflect the purpose of the study?
Research design Is the research design clearly stated? Does it appear appropriate for the purpose of the research? Is it logically connected to the sampling method and statistical analysis
Dependent and independent variables Can you identify the dependent and independent variables ( if appropriate)? Is the variable operationally defined?
Definitions Is there any operational definitions and are those presented and discussed? Are the definitions consistent with the conceptual framework?
Instrumentation What instruments were used to collect the data? Was the reliability and validity of the instruments discussed or identified?
Sample Was the size/ description of the sample stated? Was there a description of how the sample was identified and collected? Was the sample appropriate to represent the population of the study?
Ethics Was human rights protected? Did the study identify IRB clearance?
Data collection How was the data collected? Was the method of data collection clearly described? Does this appear appropriate for the purpose of the study?
Data Analysis Was the data analysis procedures clearly stated and discussed? Does it appear appropriate for the study?
Conclusions and Recommendation Does the authors summarize the research, identify strengths and weaknesses and make recommendations for future study?
Your conclusions After you have reviewed and discussed the above steps, what is your conclusions about the appropriateness and usefulness of the article? Can you use the information in your practice? If so how?
